[Koha] Out of memory

[Rubeno Fernández]

It's true, by default Digital Ocean's droplets are created without any swap 
space. Actually, they recommend not to enable it on their solid state disks:

"Although swap is generally recommended for systems utilizing traditional 
spinning hard drives, using swap with SSDs can cause issues with hardware 
degradation over time. Due to this consideration, we do not recommend enabling 
swap on DigitalOcean or any other provider that utilizes SSD storage. Doing so 
can impact the reliability of the underlying hardware for you and your 
neighbors.
If you need to improve the performance of your server, we recommend upgrading 
your Droplet. This will lead to better results in general and will decrease 
the likelihood of contributing to hardware issues that can affect your 
service."

I guess it's my choice between being cheap or being a good customer.
